【摘要】 计量技术规范推荐方法在流程工业在线计量仪表检定周期评定中存在不足,提出了一种针对这类仪表的检定周期优化方法。首先,利用Markov状态空间法得到仪表的可用性指标,然后将质量损失函数引入到检定周期寻优目标函数中,从而实现可用性和成本双约束条件下仪表最优检定周期的准确定量计算。最后,以某流程工业企业在线仪表检定周期优化应用为例,验证了该种方法的有效性。更多还原

【Abstract】 Considering the drawbacks of the recommended methods in determining the calibration interval of online measurement instruments in process industry,a method for optimizing the calibration interval of this kind of instruments is proposed.Firstly,the availability indices of the instruments are obtained using Markov state- space method.And then the Taguchi quality loss function is introduced into the objective function for accurately determining the optimal calibration interval under constraints of availability and cost.Finally,the proposed method is applied in a process industry,and the results show its effectiveness.更多还原
